一、前言 国际原子能署(IAEA)于1984年下半年组织了马肾(编号H-8)中镉和其它元素含量分析的实验室间比对工作.据IAEA 1985年1月进度报告统计,全世界有32个国家的63个实验室用不同的分析方法(包括各种核的、和非核的分析方法)参加了这项比对工作。我们实验室用中子活化法测定了该马肾中的Cd、Co、Cs、Fe、Rb、Sc、Se和Zn八个元素,所得结果与其它实验室的结果符合良好。
I. Introduction The International Atomic Energy Agency (IAEA) organized an inter-laboratory comparison of the contents of cadmium and other elements in Ma Shen (No. H-8) in the second half of 1984. According to IAEA’s January 1985 progress report, Sixty-three laboratories in 32 countries around the world participated in this alignment with different analytical methods, including various nuclear and non-nuclear analytical methods. The contents of Cd, Co, Cs, Fe, Rb, Sc, Se and Zn in the kidney were measured by neutron activation in our laboratory. The obtained results are in good agreement with those of other laboratories.
